The form of a wing structure under the definite air pressure during the flight of an athlete jumper wing of the wing-suit has been considered. The wing construction consists of a number of similar elements. The cylindrical surface with a cross-section resembling the are pulled in a chord was chosen as a geometric base element model of each wing segment. From the general laws of fabric mechanics applied to the selected geometrical model we worked out the basic system of differential equations. The above mentioned system links the amount of fabric tension, the shape of cross-section of a wing membrane and the athlete airspeed. The dependence of the cross-section area of the wing upon the dimensions of its segments and their number was shown. It was proved that the cross-section area of the wing decreased, if the number of segments was reduced. As a result, the optimal number of the wing segments securing minimal wind resistance of the wing-suit has been theoretically identified.
